Global Sustainability Jam is a global event where lots of enthusiastic people all over the world gather to "jam" on sustainable ideas for a better world. During the 48-hour jam in October 2011, I participated in the Norwegian workshop. The assignment was to create something that was both sustainable as well as it had to do with the topic ”playground”.

We quickly divided into a group of 9 people and decided we wanted to create a service that rewarded the walkers, and encouraged them to choose walking over car or taxi, also by night. Walking in the dark, especially in places like a dark ally or a park, (we have called these places blind spots) might feel unsafe and uncomfortable. We designed a service called PopSpots; by the use of your cell phone you can activated your surroundings and make it fun, playful and safe to walk at night. We didn't want to create a system that tells you to be safe, we wanted to create something that made you have fun, and actually forget that you're afraid.

On the team: Nina Lysbakken, Line Barkved, Maciej Warchal, Alexandru Stanoi, Ioana Benjamin, Victoria Utheim, Ann Kathrin Waage, Line With and me, Julia Edin.

Our concept won the Norwegian challenge.
